Webb19 maj 2024 · Gate control theory suggests that the spinal cord contains a neurological 'gate' that either blocks pain signals or allows them to continue on to the brain. This theory is often used to explain both phantom and chronic pain issues . Unlike an actual gate, which opens and closes to allow all things to pass through, the gate in the spinal cord ... When you experience a negative feeling, such as pain from a bump or an itch from a bug bite, a common reaction is an attempt to eliminate the feeling by rubbing the painful bump or scratching the itchy bite. Gate control theory asserts that activation of nerves that do not transmit pain signals, called nonnociceptive fibers, can interfere with signals from pain fibers, thereby inhibiting pain.
